Enterprise Inventory Management System (C++ OOP) 📦🏢

An advanced C++ console-based Enterprise Inventory Management System designed to simulate large-scale warehouse operations, handling diverse product categories with distinct storage, risk assessment, and expiry requirements[cite: 3].

This project demonstrates core Object-Oriented Programming (OOP) concepts including a multi-level inheritance hierarchy, dynamic polymorphism, generic templated logging, manual dynamic memory management (Rule of Three), and complex inter-class relationships[cite: 3].

🌟 Key Features

• Deep Inheritance Hierarchy (3+ Levels): Categorizes items into specialized sub-types such as FragileElectronics or PerishableGrocery[cite: 3].
• Dynamic Polymorphism: Virtual dispatch for real-time inventory operations like calculateRisk(), displayStatus(), and applyDiscount() across 10+ distinct classes[cite: 3].
• Risk & Expiry Management: Automated evaluation for high-risk fragile shipments and expired grocery stock[cite: 3].
• Supplier & Stock Integration: Link products to specific suppliers, order restocks, and generate invoices[cite: 3].
• Advanced Operator Overloading: Custom behavior for subscript [] (aisle shelf access), + (stock merging), and << (stream reports)[cite: 3].
• Generic Audit Logging (TransactionLog<T>): Template class to record actions and generate audit trails for any entity type (Product, Supplier, etc.)[cite: 3].
• Clean Architecture & Memory Safety: Strict encapsulation, zero memory leaks through proper memory management (Rule of Three), and complete header/source code separation (.h and .cpp)[cite: 3].

🏗️ System Architecture & Class Structure

🧬 Class Hierarchy & Relationships

1. Product (Abstract Base Class): Root class containing common attributes (productID, price, quantity) and pure virtual functions (displayStatus(), calculateValue())[cite: 3].
2. ElectronicProduct: Inherits from Product (Tech base with voltage, warranty)[cite: 3].
   • FragileElectronics: Inherits from ElectronicProduct (Specialized tech with fragilityRating, calculateShippingRisk())[cite: 3].
3. GroceryProduct: Inherits from Product (Food base with calories, isHalal)[cite: 3].
   • PerishableGrocery: Inherits from GroceryProduct (High-maintenance food with expiryDate, checkExpiry())[cite: 3].
   • NonPerishable: Inherits from GroceryProduct (Shelf-stable food with shelfLifeYears)[cite: 3].
4. ClothingProduct: Inherits from Product (Apparel base with size, fabric)[cite: 3].
5. Supplier: Associated with Product to track supplier contracts and process restock orders[cite: 3].
6. InventorySection: Composes Product* lists to manage stock inside aisles (addStock(), sortByID())[cite: 3].
7. Warehouse: Aggregates InventorySection objects to manage global inventory stats and locate shortages[cite: 3].
8. TransactionLog<T>: Templated audit logger tracking warehouse events generics[cite: 3].

💻 OOP Concepts Applied

Concept	Implementation Details
Deep Inheritance	3-level branching hierarchy (Product ➔ GroceryProduct ➔ PerishableGrocery)[cite: 3]
Polymorphism	Overridden virtual functions dispatched at runtime via base class pointers (Product*)[cite: 3]
Encapsulation	Protected/private member variables with strict validation setters[cite: 3]
Memory Management	Custom destructors, copy constructors, and copy assignment operators (Rule of Three)[cite: 3]
Operator Overloading	Overloaded [], +, ==, and << operators for intuitive operations[cite: 3]
Templates	Generic TransactionLog<T> class for tracking multi-entity audit trails[cite: 3]
Relationships	Explicit modeling of Composition, Aggregation, and Association[cite: 3]
